Question about 1995 GMC Sierra C1500
The truck runs fine when it is cold or damp out, only does this when weather is warmer or engine is hotter. Which means it runs fine in the winter months and acts up in the summer months. The spark plugs, distubutor cap, wires all have been recently changed and did not make a difference. Also when pulling a travel trailer, as the engine heats up, the vibration and shaking get worse and transmission fluid comes out under the truck somewhere and sprays the front of the trailer. In order to keep driving the truck has to be shut off for hours to cool down. My mechanic is stumped, nothing has led to the computer, because when a computer acts up eventually it will just quit. This has been going on for a year. Any ideas? thanks

First make sure you have no air in the system, and coolant level is full. Then with the engine idling make sure the fan turns on at running temperature. If it does not this is what is causing the over heating problem.
